In one embodiment, as shown in Fig. 2, providing a kind of travelling data analysis method, it is applied to Fig. 1 in this way In server for be illustrated, comprising the following steps:
Step 202, the travelling data of target vehicle is obtained;Travelling data includes driving image.
Server makes full use of the travelling data of automobile data recorder acquisition and recording, according to preset time frequency collection target carriage Travelling data.Travelling data includes multiframe driving image and every frame line vehicle image corresponding running time.
Step 204, identification region is determined in driving image.
Certain area around target vehicle is determined as identification region in driving image by server.For example, can be by mesh Mark right ahead, dead astern, at least the region of the preset area of side is identification region in left or right side.Preset area It can be fixed value, be also possible to the dynamic values such as the preset ratio of driving image.
Step 206, identification vehicles identifications appear in vehicle near identification region, record the vehicle location of vehicle nearby.
Vehicles identifications can be license plate number etc..Identification region includes multiple subregions.Server is according to attachment vehicle Which subregion of identification region, determines the vehicle location of each neighbouring vehicle.
Step 208, by comparing the variation of the vehicle location of vehicle nearby in adjacent multiframe driving image, judge target carriage Whether there is passing behavior.
Adjacent multiframe can be the preset quantity frame number acquired recently, such as 3 frames.It is readily appreciated that, the frame of comparison driving image Number can according to need free setting, without limitation.Some neighbouring vehicle license plate marks are in preset quantity frame line vehicle image In may only framing in the middle driving image in occur.Each vehicle nearby is identified to only one equal vehicle position for the first time It sets, as driving number of image frames increases, the vehicle location of storage is gradually increased, but at most only deposits preset quantity road location. In other words, the quantity of the vehicle location of vehicle is less than or equal to preset quantity near each of storage.
Server obtains the variation tendency of each vehicle nearby vehicle location in multiframe driving image, judges that the variation becomes Whether gesture is the first preset trend.If so, server determines target vehicle, in corresponding running time, there are passing behaviors.
Step 210, it is counted according to the overtake other vehicles frequency of the judging result to target vehicle.
According to judging result, the overtake other vehicles frequency of the server to target vehicle in statistical time range is counted.Statistical time range can To be that target vehicle car owner initiates a period of time before vehicle insurance handles request, such as half a year.The frequency of overtaking other vehicles, which can be, overtakes other vehicles time Several ratios with statistical time range time span.
In another embodiment, number of the server to target vehicle in statistical time range passed vehicle (is denoted as passed vehicle time Number) it is counted.For example, server judges nearby whether vehicle variation tendency of vehicle location in multiframe driving image is pre- If second of trend.If so, server determines target vehicle, in corresponding running time, there are passed vehicle behaviors.At this point, overtaking other vehicles The calculating of the frequency may is that the frequency of overtaking other vehicles=number of overtaking other vehicles/(number of overtaking other vehicles+passed vehicle number).
Step 212, the corresponding vehicle insurance expense of target vehicle is calculated according to the frequency of overtaking other vehicles.
Server can preset a variety of corresponding vehicle insurance expense adjustment in frequency section and every kind of frequency section of overtaking other vehicles of overtaking other vehicles Ratio.Server determines that target vehicle is overtaken other vehicles frequency section of overtaking other vehicles belonging to the frequency, according to the corresponding vehicle in frequency section of overtaking other vehicles Dangerous expense adjustment ratio increases or reduces basic vehicle insurance expense, obtains the corresponding vehicle expense of target vehicle.
In the present embodiment, according to the multiframe of the target vehicle of acquisition driving image, the identification in driving image can be determined Region;It is identified whether to appear in identification region according to license plate, can identify the corresponding vehicle nearby of target vehicle;According to record Vehicle location of the neighbouring vehicle in adjacent multiframe driving image, can compare the variation of vehicle location;According to vehicle location Variation, it can be determined that target vehicle whether there is passing behavior;According to judging result, can count to obtain overtaking other vehicles for target vehicle The frequency;According to the frequency of overtaking other vehicles, the corresponding vehicle insurance expense of target vehicle can be calculated.Due to carry out automatically travelling data acquisition and Analysis, and vehicle insurance expense is directly calculated based on the analysis results, vehicle insurance expense computational efficiency not only can be improved, can also be improved meter Calculate result objectivity and accuracy.In addition, by carrying out identification region division to driving image, and based on identification region near Vehicle carries out position statistics, judges that target vehicle whether there is according to the change in location of neighbouring vehicle relative target vehicle and overtakes other vehicles Behavior can be improved passing behavior judgment accuracy compared to general movement images similarity, and then improve vehicle insurance expense and calculate Accuracy.
In one embodiment, the step of determining identification region in image of driving a vehicle, comprising: the knowledge in identification driving image Other starting point and lane sideline;Target vehicle and the following distance with lane front truck are obtained, identification distance is determined according to following distance; Identification region is determined based on identification starting point and identification distance.
Automobile data recorder is usually the vehicle condition and road conditions acquired around target vehicle centered on target vehicle, is thus serviced Device can be by the position (i.e. target vehicle position) for the image lower middle side that drives a vehicle labeled as identification starting point.On pavement of road Would generally there are lines, arrow, text, object marking, protuberant guide post and delineator etc. for guiding to traffic participant transmitting, limit The traffic marking of the traffic informations such as system, warning.Wherein, lane sideline, which refers to, divides vehicle in the user where target vehicle on road The lines in road.
If target vehicle exists with lane front truck in image of driving a vehicle, server obtains target vehicle distance with lane front truck Image distance calculates the following distance of target range according to image distance and image taking ratio.If target in image of driving a vehicle Vehicle is not present with lane front truck, then server obtains image taking distance, according to image taking distance and image taking ratio Example, calculates the following distance of target range.Server carries out logic of propositions operation to following distance, obtains identification distance.For example, Following distance * 3/2=identifies distance.In another embodiment, can the drive a vehicle preset ratio of image of identification distance is moved State determines, is also possible to fixed value, without limitation.
Identification region can be the quadrangle that side length is determined according to preset length and identification distance.Wherein, identification starting point is The midpoint on a side in quadrangle.Fig. 3 A is the wherein 1 frame line vehicle image that the automobile data recorder of target vehicle is shot.Such as Fig. 3 A institute Show, which can be to identify that starting point is the isosceles trapezoid of following terminal, wherein lower edge lengths It can be image lane width * 3 respectively with upper edge lengths, highly can be identification distance.Image lane width can be one Width of the lane in driving image.It is readily appreciated that, in the different images height of driving image, corresponding image lane width is not Together.For example, the image lane width of picture altitude can be 5cm where following;The image lane of picture altitude is wide where top Degree can be 3cm.
Server identifies vehicle near target vehicle in driving image.In the example above, exist in identification region Five vehicles, wherein can recognize license plate mark have A, B, C and D tetra-, although vehicle E can recognize its license plate mark Know, but it is in identification region, so that vehicle includes A, B, C and D near target vehicle.
In the present embodiment, image procossing is carried out to driving image, is dynamically determined target vehicle in the knowledge of each driving image Other region selects mode that region division accuracy can be improved compared to general frame;Dynamic limitation is carried out to identification region, it can be right It needs the content of further detail image processing precisely to be limited, not only improves accuracy of identification, need image due to having limited The data volume of processing, can also be improved recognition efficiency.
In one embodiment, the vehicle location of vehicle nearby is recorded, comprising: generate according to identification distance and divide equally sideline; Identification region is divided into multiple subregions based on respectively sideline and lane sideline;According to the position of subregion where neighbouring vehicle Determine corresponding vehicle location.
Different according to the number for dividing equally identification region, respectively the quantity in sideline is different.For example, the respectively quantity in sideline It can be the number -1 for dividing equally identification region.The length that difference divides equally sideline can be different.Respectively the length in sideline can also To be the integral multiple of image lane width * 3.For example, after carrying out region division to the driving image of the example above, it is available such as Image shown in Fig. 3 B.In figure 3b, server is according to identification distance by identification region trisection.Specifically, server according to Number identification distance and divide equally identification region generates three and divides equally sideline.Wherein, respectively the length in sideline 1 can be with It is image lane width * 3, respectively sideline 2 and the length in respectively sideline 3 can be image lane width * 1 respectively.
Server can construct coordinate system based on identification region, and then determine that divide equally sideline and lane sideline is expert at respectively The image coordinate of vehicle image.Server spells a plurality of respectively sideline and lane sideline in identification region according to image coordinate It connects, and then identification region is divided into multiple subregions, and the coordinate position according to subregion in a coordinate system, by multiple difference Labeled as upper region, middle region or lower region.As shown in Figure 3 C, in the example above, identification region is divided into 6 sons by server The maximum subregion 1 of ordinate is labeled as upper region by region, and by ordinate time height and identical subregion 2 and subregion 3 divide It Biao Ji not be region, it is ordinate is minimum and identical subregion 5 and subregion 6 are respectively labeled as lower region.It is readily appreciated that, It is lower than 3 parts to the number for dividing equally identification region, then it is different that certain sub-regions can be further broken into multiple ordinates Intermediate region after according still further to aforesaid way be divided into three kinds of upper, middle and lower region.It is more than to the number for dividing equally identification region 3 parts, then can be merged into behind an intermediate region with the adjacent subregion of multiple ordinates be divided into according still further to aforesaid way, In, lower three kinds of regions.
According to the position of subregion where neighbouring vehicle, server can determine corresponding vehicle location.For example, neighbouring vehicle The vehicles identifications of A appear in region, then it is upper for can recorde the vehicle location of neighbouring vehicle.In another embodiment, The vehicle location of neighbouring vehicle can be specific coordinate of the vehicles identifications in identification region respective coordinates system of neighbouring vehicle A, right This is with no restriction.
It is worth noting that, identification region can also be determined using other modes, it can also be using other modes to knowledge Other region is divided, and the present embodiment is merely given as can determine the one of the vehicle location variation of neighbouring vehicle relative target vehicle Kind exemplary instrumentation.
In the present embodiment, identification region is further divided into convenient for determining vehicle relative target vehicle location variation nearby Multiple subregions, multiple subregions based on this model split, can simplify identification nearby vehicle relative target vehicle position The recognizer of variation tendency is set, and then improves passing behavior analysis efficiency.
In one embodiment, as shown in figure 4, by comparing adjacent multiframe driving image in nearby vehicle vehicle location Variation, judge target vehicle with the presence or absence of passing behavior, i.e., the step of passing behavior determines, comprising:
Step 402, according to adjacent multiframe driving image in vehicle location, generate nearby vehicle driving feature to Amount.
In one embodiment, travelling data includes running time;According to the vehicle position in adjacent multiframe driving image It sets, generates the driving feature vector of vehicle nearby, comprising: according to running time, determine the traversal order of multiframe driving image;Root According to traversal order, successively traversed to whether every frame line vehicle image neighbouring vehicle occurs;By attachment vehicle in a frame or multiframe Vehicle location in driving image is respectively labeled as the vector element of different order;To the adjacent vector element of each attachment vehicle Carry out duplicate removal processing.The driving feature vector of corresponding vehicle nearby is generated based on multiple vector elements after duplicate removal.
Server traverses collected multiframe driving image according to the sequencing of running time.It is readily appreciated that, Some neighbouring vehicles acquire recently multiframe driving image in may only framing in the middle driving image in occur.Therefore, Server judges that the license plate mark of vehicle nearby whether there is in the first frame driving image of acquisition in ergodic process.If Exist in first frame driving image, vehicle position mark of the attachment vehicle in first frame driving image is first by server The vector element of sequence.Server continues to judge whether the license plate mark of neighbouring vehicle deposits in the next frame driving image of acquisition ?.If existing in next frame driving image, vehicle position mark of the attachment vehicle in next frame driving image is by server Whether the vector element of next sequence, the license plate mark for continuing vehicle near Ergodic judgement deposit in the driving image of next frame again It is so repeating to traverse, the image until last frame is driven a vehicle, is obtaining each corresponding multiple vector elements of vehicle nearby.Under if It is not present in one frame line vehicle image, server continues traversal next frame driving image again in the manner described above.
According to the acquisition of vector element sequence, multiple vector elements are ranked up by server, formation element queue.Service Device judges whether each vector element repeats with previous vector element in element queues.If repeating, server will be corresponded to Vector element deleted from element queues, based on the element queues after duplicate removal generate the driving feature of corresponding vehicle nearby to Amount.For example, in the example above, the corresponding driving feature vector of neighbouring vehicle A can be [on, in, under], B pairs of neighbouring vehicle The driving feature vector answered can be [under, in, on], and the corresponding driving feature vector of neighbouring vehicle C can be [on, in], attached The corresponding driving feature vector of nearly vehicle D can be [in, under].It is readily appreciated that, there is no similar presence such as [in, under, under] The duplicate driving feature vector of adjacent vector element.
Step 404, the first property value for calculating driving feature vector, compares whether first property value reaches threshold value.
First property value can be the quantity that driving feature vector includes vector element.Threshold value can be fixed value, and such as 3. Threshold value is also possible to according to the numerical value for being dynamically determined the number that image is divided equally of driving a vehicle.
Step 406, if reaching threshold value, the second attribute value of driving feature vector is calculated.
If the first property value for feature vector of driving a vehicle is less than threshold value, whether the relatively corresponding vehicle nearby of server target vehicle Generation passing behavior, which is not done, to be determined.For example, the first property value of neighbouring vehicle C and neighbouring vehicle D are 2, small in the example above In threshold value 3.
If the first property value for feature vector of driving a vehicle is equal to threshold value, server, which further calculates, drives a vehicle the of feature vector Two attribute values.Second attribute value can be the category of the variation tendency of the vehicle location for characterizing neighbouring vehicle relative target vehicle Property value.
Step 408, judge whether the second attribute value is Target Attribute values.
Step 410, if Target Attribute values, marking target vehicle, there are passing behaviors.
Server has preset plurality of target attribute value and the associated judgement result of every kind of Target Attribute values.For example, upper It states in citing, corresponding second attribute value of neighbouring vehicle A is Target Attribute values 3, indicates target vehicle relatively nearby vehicle A preceding Into, it is possible to determine that nearby passing behavior occurs target vehicle for vehicle A relatively.
In the present embodiment, passing behavior parser is simplified, passes through the first property value to driving feature vector Whether meet corresponding preset condition respectively with the second attribute value, that is, can determine whether target vehicle occurs passing behavior, improves Passing behavior analysis efficiency.
In one embodiment, the corresponding vehicle insurance expense of target vehicle is calculated according to the frequency of overtaking other vehicles, comprising: be based on road map As the deviation frequency and the anti-collision warning frequency of identification target vehicle;Hypervelocity based on vehicle sensed data statistics target vehicle The frequency and the zig zag frequency;The bad steering record for crawling target vehicle, the wine of statistics target vehicle is recorded based on bad steering Drive the frequency and the liability accident frequency;According to the frequency of overtaking other vehicles of statistical time range, the deviation frequency, the anti-collision warning frequency, hypervelocity frequency Secondary, the zig zag frequency, the drunk driving frequency and the liability accident frequency, determine the driving behavior security level of target vehicle;According to driving The vehicle insurance expense of behavior safety level adjustment target vehicle.
Server judges mesh by comparing the change in location in target vehicle opposite lane sideline in adjacent multiframe driving image Marking vehicle whether there is deviation behavior.When there are deviation behavior, deviation frequency of the server to target vehicle It is secondary to be counted.Whether server is less than preset value by comparing following distance, judges target vehicle with the presence or absence of anti-collision warning Behavior, when there are anti-collision warning behavior, server counts the anti-collision warning frequency of target vehicle.
Travelling data further includes vehicle sensed data.Vehicle sensed data includes speed change data and direction change number According to.Server obtains corresponding roadway speed limit data according to driving image, is become based on roadway speed limit data and speed Change data, judges target vehicle with the presence or absence of hypervelocity behavior.Exceed the speed limit behavior if it exists, the hypervelocity frequency of the server to target vehicle It is counted.Server judges target vehicle with the presence or absence of zig zag behavior according to direction change data.Zig zag row if it exists For server counts the zig zag frequency of target vehicle.
